The Scaling Of Analog Command; The Timing Diagram In Speed Mode - Delta ASD-A2R-0221 Series User Manual

Chapter 6 Control Mode of Operation ASDA-A2R Series

6.3.4 The Scaling of Analog Command

The motor speed command is controlled by the analog voltage deviation between V_REF
and VGND. Use parameter P1-40 to adjust the speed-control slope and its range.
Related parameter: Please refer to Chapter 8 for further information.

Command
1 ） OFF means the contact point is open while ON means the contact
point is close.
2 ） When it is in Sz mode, the speed command S1 = 0; When it is in S
mode, the speed command S1 is the external analog voltage input.
3 ） When the servo drive is On, please select the command according to
SPD0~SPD1 status.
The slope is determined by P1-40.
Analog Input Voltage (V)
Setting
Set P1-40 to 2000. If the input voltage is
10V, the speed command will be
2000r/min.
